Description

  The present invention relates to a coil manufacturing apparatus that winds a wire fed from a nozzle and manufactures a coil.

  Conventionally, as a chip coil used in a small electronic device or the like, a coil is obtained by winding a wire around a winding body of a core having flanges at both ends, and the wire formed at the end of the coil is formed at the flange What is fixed to is known. As a device for manufacturing such a chip coil, a wire feeder that feeds a wire from a nozzle with a constant tension, a clamp device that grips the end of the wire fed from the nozzle, and a core that supports the core There has been known one provided with a winding jig that rotates and winds a wire fed from a nozzle around a rotating core (for example, see Patent Document 1).

  In this coil manufacturing apparatus, the core is held by the winding jig, and the winding jig is rotated together with the clamping device that holds the end portion of the wire, and the wire fed from the nozzle is supported by the winding jig. It is wound around the core. In the processing of the wire in the chip coil manufacturing apparatus, after the winding is completed, the wire at the end of the coil is soldered to the electrode formed on the collar to fix the wiring.

  Thus, although conventional coil manufacturing consists of gripping, winding, and wiring of the core to the winding jig, a plurality of winding jigs are prepared for relatively small chip coils. While the winding is performed on the core held by one winding jig, the core is held by another winding jig and the core after winding is held. By performing the wiring work in the winding jig, each work is performed simultaneously to increase the number of coils produced per unit time.

  In this way, in coil manufacturing in which the core is separately gripped, wound, and wired, the wire taken out from the nozzle and wound around the core is cut once at the end of the winding. In this state, it is necessary to transport the winding jig together with the core to the next wiring process. In this case, the wire rod is cut by moving a nipper device capable of cutting the wire rod by electric or fluid pressure three-dimensionally by a three-axis movement mechanism, and sandwiching the wire rod between a pair of cutting teeth of the nipper device. It has been proposed to cut the wire by closing the cutting teeth of each other (see, for example, Patent Document 2).

  However, since the wire cutting device in the conventional coil manufacturing apparatus moves the nipper device by the triaxial moving mechanism, the triaxial moving mechanism becomes relatively large, and the entire apparatus becomes large. was there.

  Further, when the wire extending from the core to the nozzle is cut after the winding, the coil wound around the core may be loosened due to the elasticity of the wire and the wire may be unwound from the core. For this reason, in an apparatus in which the winding jig is moved to perform winding and wiring at different positions, it is necessary to prevent the wire rod cut after the winding from being unwound from the core.

  An object of the present invention is to cut a wire end wire of a coil made of a wound wire material without increasing the size of the device, and to remove both the wire start wire end wire and the wire end wire before wiring. An object of the present invention is to provide a coil manufacturing apparatus capable of preventing the wire rod held and wound from being unwound.

  A coil manufacturing apparatus according to the present invention includes a nozzle that feeds a wire, a winding jig that winds the wire fed from the nozzle, and a clamp device that grips an end of the wire fed from the nozzle. It is an improvement of the device.

  The characteristic configuration includes a substrate attached to the winding jig such that one main surface faces the periphery of the winding jig, and a first clamping tool that clamps the wire together with one side of the substrate, A second holding tool that holds the wire together with the other side of the substrate, a cutter member that is superimposed on the other main surface of the substrate and pivotally supported by the winding jig, and the cutter member is rotated to rotate the cutter member. An urging means for urging the cutter blade away from one side of the substrate, and a wire extending from the winding jig to the nozzle by moving the nozzle in the three-axis direction to the first side of the substrate and the first A nozzle moving mechanism that is inserted between both the clamping tool and the cutter blade separated from one side of the substrate and one side of the substrate, and a winding device by moving the clamp device in three axial directions. Wire extending from the fixture to the clamping device between the other side of the substrate and the second clamping fixture And 蓄線 moving mechanism through a cutter member is rotated are in place and a cleavable-configured member rotating means inserted through so the wire between the cutter blade and one side of the substrate.

  When the storage movement mechanism also serves as the member rotation means, the storage movement mechanism is configured so that the clamp device is brought into contact with the cutter member and the cutter member in contact with the clamp device is rotatable.

  When the winding jig is pivotally supported by the base, a storage movement mechanism is provided on the base and includes a fluid pressure cylinder that causes the retracting rod to be retracted by fluid pressure. The fluid pressure cylinder contacts the retracting rod with the cutter member. It is also possible to make the cutter member in contact with the retracting rod pivotable.

  In the case of further comprising a rotating means for rotating the nozzle or the clamp device around the winding jig, the rotating means rotates the nozzle or the clamping device in the same direction at a speed faster than the rotating speed of the winding jig. The wire rod fed out from the nozzle to the winding jig and the wire rod gripped by the clamp device and pulled out in advance from the nozzle can be wound up.

  In the coil manufacturing apparatus of the present invention, since the cutter member is provided around the winding jig, the wire can be cut only by rotating the cutter member by the member rotating means. Therefore, the coil manufacturing apparatus according to the present invention does not use a nipper device or a triaxial moving mechanism that moves the nipper device conventionally required for cutting the wire.

  Since the cutter member for cutting the wire is provided around the winding jig, it does not become a large-sized one, and this cutter member is superposed on the substrate holding the wire together with the first and second holding tools. Therefore, even if the wire material at the end of winding of the obtained coil is cut, the wire material at the beginning and end of winding of the coil is held by the substrate and the holding tool. Therefore, the coil manufacturing apparatus in the present invention holds both the winding start and end windings of the obtained coil and then moves the winding jig for wiring, for example. This makes it possible to prevent the wound wire rod from being unwound.

  Further, the nozzle or the storage means is rotated by the rotation means in the same direction at a speed faster than the rotation speed of the winding jig, and the wire rod fed out from the nozzle to the winding jig and the wire rod stored in the storage means If both are wound, an α-wound coil can be manufactured in which the wire material at the beginning and end of winding are both outer circumferences.

  Even when such an α-winding coil is obtained, the wire at the end of winding of the obtained coil is cut, and the wound wire can be unwound while holding both the wire at the start and end of winding of the coil. It becomes possible to prevent this.

Then, the cutter member 74 is rotated so that the cutter blade 74 c is moved away from one side portion at the tip of the substrate 71. When the operation portion 74d is brought close to the fixture 76 against the urging force of the coil spring 80, the gap between the cutter blade 74c and one side portion at the tip of the substrate 71 is eliminated as shown by a one-dot chain line. If the wire 12 is sandwiched between the one side portion at the front end of the substrate 71 and the first sandwiching tool 72, the sandwiched wire 12 can be cut.

  As shown in FIG. 5, the presser 77 sandwiches the first and second holding tools 72 and 73 and the cutter member 74 pivotally supported by the pivot pins 76 g and 76 h of the fixture 76 together with the presser 77.

It is configured to be clamped.

  Next, the operation of the coil manufacturing apparatus will be described.

  In the coil manufacturing apparatus 10 of the present invention, the core 11 is gripped by the winding jig 14 by gripping means (not shown) provided side by side in the X-axis direction, and the winding jig 14 is moved to reach the winding means. In the winding jig 14, winding is performed on the core 11 held by the winding jig 14, and then the winding jig 14 is moved again, and wiring is performed by wiring means (not shown).

  Although not shown, the gripping means grips the core 11 on the winding jig 14 by operating a retracting rod of an air cylinder (not shown) provided facing the operation rod 26 of the winding jig 14 upward. The rod 26 is raised, thereby widening the space above the fixed-side gripping member 21a and the movable-side gripping member 21b in the chuck 21 shown in FIG. And one collar part 11a of the core 11 is horizontally mounted in the notch part 21c in the fixed side holding member 21a. Thereafter, an unillustrated air cylinder retracting rod is inserted to lower the operating rod 26 to narrow the distance between the fixed gripping member 21a and the movable gripping member 21b above the pivot point, thereby horizontally extending the notch 21c. One of the flanges 11a placed is gripped.

  The movement of the plurality of winding jigs 14 holding the core 11 in this way is performed by rotating the ball screw 29 shown in FIGS. 1 to 3 by a motor (not shown). Since the ball screw 29 is screwed to the movable table 18, when the ball screw 29 is rotated, the movable table 18 moves together with the base 16 and the plurality of winding jigs 14 provided on the base 16 in the X-axis direction. It moves and moves from the gripping means to the winding means.

  In this embodiment, a case where winding is performed on the core 11 in the winding means and an α-winding coil 17 is obtained by this winding will be described. Then, in the winding to the core 11 in this winding means, a wire rod drawing process for holding the wire rod 12 fed from the nozzle 31 in the wire rod feeder and pulling out a predetermined length, and a winding jig 14 are provided. The winding step of rotating the wound wire 12 around the core 11 provided on the chuck 21 and the wire 12 fed from the nozzle 31 by rotating the nozzle 31 in the same direction as the core 11. An α-winding coil forming step of forming the α-winding coil 17 by winding the wire 12a and 12b on both ends of the α-winding coil 17 by the substrate 71 and the first and second holding tools 72 and 73; A wire cutting step of cutting the wire 12b extending from the core 11 to the nozzle 31 can be performed.

  In the following, although each step in the winding to the core 11 will be described in detail, in this embodiment, which has two bases 16 and is provided with five winding jigs 14 respectively, Winding is simultaneously performed on the core 11 held by the five winding jigs 14 in the base 16. And since the winding to the core 11 in each winding jig | tool 14 becomes the same operation | movement, the winding to the core 11 in one winding jig | tool 14 shall be demonstrated below representatively. .

<Wire drawing process>
In this step, the wire 12 fed from the nozzle 31 is held and pulled out for a predetermined length. The wire rod 12 is wound around the drum 45, and the wire rod 12 fed out from the drum 45 is guided to a wire rod guide 46a at the tip of the tension bar 46, and the insertion hole 39a of the rotating member 39 is passed through the auxiliary pulley 38b from the wire rod guide 46a. Wire so as to pass through.

  The wire 12 in this embodiment is a so-called square wire having a square cross section, and the wire 12 having the square wire is passed through the insertion hole 39a and then passed through the feed hole 31a of the nozzle 31. .

  And as shown in the enlarged view of FIG. 1, the end of the wire 12 passed through the feeding hole 31a is drawn obliquely upward. By bending this diagonally upward, the wire 12 is locked to the hole edge of the feeding hole 31a and is prevented from returning toward the tension device 42 side.

  In this wire rod drawing process, the clamp device 53 is moved by the storage movement mechanism 54, and the wire rod 12 drawn out from the nozzle 31 and bent obliquely upward by the holding pieces 53a and 53b is gripped.

  Thereafter, the storage device moving mechanism 54 moves the clamp device 53 again and pulls the clamp device 53 away from the nozzle 31 as shown in FIG. Thereby, the wire 12 is drawn out from the nozzle 31 by a predetermined length.

  This predetermined length is the length of the wire 12 necessary for winding one coil of the α-winding coil 17 (FIG. 14) to be obtained, and is clamped when it becomes substantially equal to the length. The movement of the device 53 is stopped, and this wire drawing process is completed.

<Winding process and α winding coil formation>
In this embodiment, the case where the winding process and the α-winding coil formation are performed simultaneously is shown.

  In this step, in the nozzle moving mechanism 33 shown in FIGS. 1 and 2, the rotating member 39 provided with the nozzle 31 is moved to above the chuck 21, and the rotation center thereof is matched with the rotation center of the chuck 21. . In this state, the rotating member 39 is lowered until the feeding hole 31a of the nozzle 31 forming a hexahedron faces the winding body 11c of the core 11.

  Next, as shown in FIG. 12, the clamp device 53 is moved so that the wire 12 drawn from the nozzle 31 follows the core 11 provided on the chuck 21. The clamp device 53 is moved by the storage movement mechanism 54 (FIG. 1).

  Then, as shown in FIG. 13, the wire 12 drawn by rotating the winding jig 14 is rewound onto the core 11 provided on the chuck 21 and at the same time, the nozzle 31 is doubled faster than the rotation of the chuck 21. The α-winding coil 17 is formed by winding the wire 12 newly fed from the nozzle 31 around the core 11 by rotating in the same direction at the rotational speed of.

  The rotation of the nozzle 31 is performed by rotating a rotating member 39 provided with the nozzle 31 by a motor 32 (FIG. 1), thereby rotating the nozzle 31 around the core 11. The rotation of the nozzle 31 rotates the periphery of the core 11 at twice the speed in the same direction as the rotation direction of the chuck 21.

  Thereby, the wire 12 newly drawn out from the nozzle 31 is simultaneously wound around the core 11 together with the wire 12 rewound in the direction indicated by the solid line arrow in FIG. At this time, the wire 12 newly fed out from the nozzle 31 is fed along the other flange portion 11b of the core 11, and is wound around the winding drum portion 11c with a bias toward the other flange portion 11b.

  On the other hand, the winding jig 14 is rotated by the motor 23 attached to the pedestal 13 shown in FIG. 1, and the wire 12 drawn out by moving the clamping device 53 away from the chuck 21 is provided on the chuck 21. Rewind to the core 11.

  When the actual rewinding is started, the storage movement mechanism 54 is obtained by bringing the clamping device 53 close to the chuck 21 at a speed substantially equal to the speed of the wire 12 to be rewound, and the wire 12 in the meantime is bent. One coil of the α winding coil 17 is prevented from expanding.

  At this time, the coil spring 60 (FIG. 10) urges the clamping device 53 in a direction away from the winding jig 14, and an error generated between the amount of the wire 12 to be rewound and the moving amount of the clamping device 53. Thus, the bending of the wire 12 between the clamp device 53 and the core 11 is surely prevented. At this time, the wire 12 rewound from the clamping device 53 is rewound along the one flange portion 11a of the core 11 and wound around the winding drum portion 11c along the one flange portion 11a.

  Thereby, both the winding start wire 12a wound by the rotation of the chuck 21 of the wire 12 drawn in advance by the clamping device 53 and the winding end wire 12b drawn out from the nozzle 31 and wound around the core 11 are provided. Α winding coil 17 (FIG. 13) is formed at the outermost periphery.

<Wire clamping process>
In this step, the wire rods 12 a and 12 b at both ends of the α-winding coil 17 are sandwiched by the sandwiching and cutting tool 70.

  First, the clamping of the wire 12a at the beginning of winding will be described. In this clamping, the clamping device 53 is moved by the storage movement mechanism 54, and the winding wire 12a extending from the clamping device 53 to the core 11 is connected to the other side portion of the substrate 71 as shown in FIG. And the second holding tool 73. Then, the wire 12 moves by shifting the other side portion of the substrate 71 downward from the upper portion, and enters between the other side portion of the substrate 71 and the second holding device 73 from the inclined surface 73f of the second holding device 73. To do. As a result, the wire 12 a at the beginning of the winding is sandwiched between the other side portion of the substrate 71 and the second sandwiching tool 73.

  In this case, since the substrate 71 and the second holding tool 73 are positioned obliquely below the α-winding coil 17, the end edge of the wire 12a extends obliquely downward from the core 11 and is held.

  Thereafter, the holding of the wire 12 a at the beginning of winding by the clamp device 53 is canceled, and the wire 12 a at the beginning of winding is released from the clamp device 53. And the clamp apparatus 53 is moved to a standby position by the storage movement mechanism 54 shown in FIG. 1, and it is made to wait until the next wire cutting process.

  In clamping the wire rod 12b at the end of winding, as shown in FIG. 14, the nozzle 31 is moved by the nozzle moving mechanism 33 (FIG. 1), and the wire rod 12b at the end of winding extending from the nozzle 31 to the coil 17 is placed on the substrate. It is inserted and passed between one side of 71 and the first clamping tool 72. Then, the wire 12 moves by shifting one side portion of the substrate 71 downward from the upper portion, and enters between the one side portion of the substrate 71 and the first holding device 72 from the inclined surface 72f of the first holding device 72. To do. As a result, the wire 12b at the end of the winding is sandwiched between the one side portion of the substrate 71 and the first sandwiching tool 72.

<Wire cutting process>
In this step, the winding end wire 12b extending from the core 11 to the nozzle 31 is cut. This cutting is performed by the member rotating means, and in this embodiment, the storage movement mechanism 54 is described as also serving as the member rotating means.

  That is, in cutting the wire 12b at the end of winding, the storage movement mechanism 54 moves the clamp device 53, and the clamping pieces 53a and 53b contact the operation portion 74d in the cutter member 74 as shown in FIG. Let Then, the operating portion 74d is moved against the urging force of the spring 80, the cutter member 74 is rotated, and the wire rod 12b at the end of winding extending from the core 11 to the nozzle 31 includes the cutter blade 74c and the substrate 71. The wire 12 inserted between one side portion is cut.

  The cut end edge of the wire 12a extending from the core 11 to the cutter member 74 exists between one side portion of the substrate 71 and the first holding tool 72, and is held between them.

  In this case, since the board | substrate 71 and the 1st clamping tool 72 are located diagonally downward from the alpha winding coil 17, the wire 12a will be in the state pulled out diagonally below.

  Thereafter, the nozzle 31 is moved to the standby position by the nozzle moving mechanism 33. Here, as shown in the enlarged view of FIG. 1, the end of the wire 12 that has passed through the feeding hole 31a of the nozzle 31 is drawn obliquely upward, so that the wire 12 is a hole of the feeding hole 31a. There is no return toward the tension device 42 until it is locked to the edge and the next winding is made.

  The α-winding coil 17 composed of the wire 12 wound around the core 11 in this way is then moved together with the core 11 and the winding jig 14 in the X-axis direction and conveyed to the wiring means. However, since the cutter member 74 is superposed on the substrate 71 that sandwiches the wire 12 together with the first and second sandwiching tools 72 and 73, even if the wire 12b at the end of winding of the obtained coil 17 is cut, The wire rods 12 a and 12 b at the beginning and end of winding of the coil 17 are sandwiched between the substrate 71 and the sandwiching tools 72 and 73.

  Therefore, the coil manufacturing apparatus 10 according to the present invention holds both the winding start and end winding wires 12a and 12b of the coil 17 and moves the winding jig 14 for subsequent wiring. Even in this case, it is possible to prevent the wound wire rod 12 from being unwound.

  When the winding jig 14 on one substrate 71 is conveyed to the wiring means, the other substrate 71 is moved together with the plurality of winding jigs 14 from the gripping means and conveyed to the winding means. The Then, the winding is started again with respect to the core 11 held by the plurality of winding jigs 14 of the other substrate 71. As a result, the wiring work in the plurality of coils in one base 16 and the winding to the plurality of cores 11 in the other base 16 are performed at the same time. It is possible to increase the number of coils 17 to be played.

  Here, although the wire rod 12b at the end of winding is cut, if a so-called square wire having a square cross section is used as the wire rod 12, the nozzle 45 is rotated and wound in the previous α-coil forming step. The wire 12 composed of the square wire is twisted between the nozzle 31 and the nozzle 31. In order to eliminate this twisting, it is preferable to remove the twist by cutting the wire 12 at the end of winding and then rotating the nozzle 31 together with the chuck 21 in the direction opposite to that during winding. The number of rotations is the same as the number of rotations at the time of winding, and after the twist is eliminated, the next wire drawing process can be started again.

  Thus, in the present invention, since the cutter member 74 is provided around the winding jig 14, the wire 12 can be cut only by rotating the cutter member 74 by the member rotating means 54. Therefore, the coil manufacturing apparatus 10 of the present invention does not use a nipper device or a three-axis movement mechanism that is conventionally required to cut the wire 12.

  The cutter member 74 that cuts the wire 12 is a flat plate provided around the winding jig 14, so that the cutter member 74 does not have a large size, and the cutter member 74 is rotated together with the winding jig 14. Therefore, an independent drive mechanism for operating the cutter member 74 is not required. Therefore, the coil manufacturing apparatus 10 according to the present invention is a relatively small device capable of cutting the winding end wire 12b of the coil 17 with a predetermined length.

  Further, the nozzle 31 was rotated in the same direction at a speed faster than the rotation speed of the winding jig 14, and the core 11 held by the chuck 21 was stored in the wire 12 fed from the nozzle 31 and the storage means 52. Since both of the wire rods 12 are wound, the α-winding coil 17 in which the wire rods 12a and 12b at the beginning and end of winding are both outer circumferences can be manufactured. Even if such an α-winding coil 17 is obtained, the wire 12b at the end of winding of the obtained coil 17 can be cut.

  In the above-described embodiment, the case where the α-winding coil 17 is manufactured by rotating the nozzle 31 at a speed faster than the rotation speed of the chuck 21 has been described. The α winding coil 17 in which both the winding start and end wire rods 12a and 12b are outer peripherally is manufactured by rotating the clamping device 53, which is the storage means 52 in the same direction at a higher speed, by the rotating means. good. Even in this case, in the present invention, both ends of the coil 12 can be held, and the wire member 12b at the end of winding of the obtained coil can be immediately cut by the cutter member 74.

  In the above-described embodiment, the nozzle movement mechanism 33 and the storage movement mechanism 54 configured by a combination of the X-axis, Y-axis, and Z-axis direction expansion and contraction actuators have been described. The present invention is not limited to this, and other types may be used as long as the object can be moved in three axial directions.

  In the above-described embodiment, a case where a so-called square line having a square cross section is used is described. However, the wire 12 is not limited to a square line, and the cross section may be a rectangle or a polygon. It may be a so-called round line that forms a circle.

  In the above-described embodiment, the case where the wire 12 is wound around the core 11 provided on the chuck 21 to obtain the α-winding coil 17 has been described. However, the core 11 is not provided and the winding jig 14 is provided. The wire 12 may be wound directly and the coil 17 may be formed around it. In this case, the winding jig 14 is preferably formed with a core around which the wire 12 is wound, instead of the chuck 21 that supports the core 11. The coil obtained by winding the wire 12 around the winding core is a so-called air-core coil composed of only the wire 12 without the core 11.

  Further, in the above-described embodiment, the case where the two bases 16 are provided and five winding jigs 14 are provided in each of the bases 16 is described. The present invention is not limited to this, and three or more bases 16 may be provided, and six or more winding jigs 14 may be provided on a single base 16.

  In the above-described embodiment, the case where the winding process and the α-winding coil forming process are performed simultaneously has been described. That is, in the above-described embodiment, the wire 12 drawn by rotating the winding jig 14 is wound around the core 11, and the nozzle 31 is rotated at twice the rotation speed faster than the rotation of the winding jig 14. The α-winding coil 17 was formed by winding the wire 12 fed from the nozzle 31 by rotating in the direction around the core 11. However, the α winding coil forming step may be performed after the winding step.

  That is, the winding jig 14 is rotated and the nozzle 31 is rotated in the same direction at the same rotational speed as that of the winding jig 14 so that the drawn wire 12 is wound around the core 11 first. A winding step for forming the coil is performed. Thereafter, the rotation of the winding jig 14 is stopped and the rotation of the nozzle 31 is continued. The wire 12 fed from the nozzle 31 is wound around the core 11 which has stopped rotating, and the other coil is adjacent to one coil. Then, the α winding coil forming step is performed. Then, at the end of the α-winding coil forming process, the α-winding coil 17 composed of both coils is formed, and thus the α-winding coil forming process may be performed after the winding process. .

  Further, in the above-described embodiment, the case where the storage movement mechanism 54 also serves as a member rotating means has been described. However, when the winding jig 14 is pivotally supported by the base 16 as shown in FIG. In addition, the member rotating means may be provided on the base 16 and provided with a fluid pressure cylinder 81 for projecting and retracting the retracting rod 81a by fluid pressure.

  The fluid pressure cylinder 81 shown in FIG. 16 shows the one in which the retractable rod 81 a is retracted by supplying and discharging compressed air, and the retractable rod 81 a is opposed to the winding jig 14 on the base 16 via the lifting cylinder 82. A case where a plurality of winding jigs 14 are provided is shown. The ascending / descending cylinder 82 has a main body portion 82b attached to the base 16 with its retracting rod 82a facing upward, and a fluid pressure cylinder 81 is attached to the upper end of the retracting rod 82a.

  The lifting / lowering cylinder 82 is configured to lower the fluid pressure cylinder 81 and to stand by at a standby position indicated by a one-dot chain line when the retracting rod 82a is immersed in the main body portion 82b. In the wire rod cutting step in which the coil 17 is formed, the elevating cylinder 82 raises the fluid pressure cylinder 81 by projecting the projecting rod 82a upward, and the cutter member 74 in the clamping cutter 70 is moved up. It is comprised so that it may oppose to the operation part 74d.

  In this state, when the fluid pressure cylinder 81 protrudes the retracting rod 81a, its tip comes into contact with the operation portion 74d, and when further protruding, the operation portion 74d moves against the urging force of the spring 80. The cutter member 74 rotates. Therefore, even in such a member rotating means, the wire rod 12b at the end of winding extending from the core 11 to the nozzle 31 and the wire rod 12 inserted between the cutter blade 74c and one side of the substrate 71 is inserted. It becomes possible to cut.
